Oenothera tetragona Roth
Comments
This species is closely related to O. fruticosa and most Virginia herbarium specimens are labelled "Oenothera fruticosa ssp. glauca." The map likely includes records for O. hybrida (O. tetragona var. hybrida [Michx.] Fern.), allegedly a Southern Blue Ridge endemic. It's worth noting that O. hybrida has been treated as a var. of both O. tetragona and O. fruticosa, again emphasizing the close taxonomic relationship of these species.
Habitat
Mesic to dry clearings, roadsides, wet meadows, mafic and calcareous fens. Frequent in the Piedmont and mountains (at lower elevations).
Native Status
Native
